Hi girls, I hope you are all fine, and everything is OK.I have no much news, I still work on the same topic, still waiting for good results, still waiting for my paper correction... At the end of this month, i will pass an exam named CAPES: this is an exam about all physics studied in our life, if we succed this exam we can work as a teacher in high school. But i don't believe on the procedure of the exam correction. I feel disappointed this period, everything in Tunisia goes wrong (no job, no god news,....).
